Change BS names while transporting

Hi

I have to Transport objects from Dev to Qas. I am using File Transport and I am downloading it to the client, Desktop. When I import it to the QAS, will the names of the Business Systems change or do we have to change them manually?

How do we include the option in SLD so that the names of Business Systems will point to the ones in Quality when it's transported ? I am maintaining only one SLD for Dev, Qas and Production

Regards
